Second language (L2) viewing with captions (i.e., L2 on-screen text) is now a proliferating as well as promising area of L2 acquisition research. The goal of the present meta-analysis was to examine (a) the relationship between captioned viewing and incidental vocabulary learning and (b) what variables related to learners, treatment, methodology,…

Yanagisawa, Akifumi; Webb, Stuart – Studies in Second Language Acquisition, 2022
The present meta-analysis aimed to improve on Involvement Load Hypothesis (ILH) by incorporating it into a broader framework that predicts incidental vocabulary learning. Studies testing the ILH were systematically collected and 42 studies meeting our inclusion criteria were analyzed. The model-selection approach was used to determine the optimal…

Yanagisawa, Akifumi; Webb, Stuart – Language Learning, 2021
The involvement load hypothesis (ILH) was designed to predict the effectiveness of instructional tasks for incidental L2 vocabulary learning. In this meta-analysis we examined 398 effect sizes from 42 empirical studies (N = 4,628) to explore (a) the overall predictive ability of the ILH, (b) the relative effects of different components of the ILH…

Uchihara, Takumi; Webb, Stuart; Yanagisawa, Akifumi – Language Learning, 2019
This meta-analysis aimed to clarify the complex relationship between repetition and second language (L2) incidental vocabulary learning by meta-analyzing primary studies reporting correlation coefficients between the number of encounters and vocabulary learning. We synthesized and quantitatively analyzed 45 effect sizes from 26 studies (N = 1,918)…

Huang, Shufen; Willson, Victor; Eslami, Zohreh – Modern Language Journal, 2012
This meta-analytic study provides a systematic statistical synthesis of the effects of output tasks on second or foreign incidental vocabulary learning. A total of 12 studies were included in this meta-analysis. Five mediator variables were examined: design quality, types of output task, time on task, genres of text, and text-target word ratios.…
